Tuna

The Tuna are several species of ocean-dwelling fish in the family Scombridae. Tunas are fast swimmers. They are warm-blooded, which enables them to live in colder waters, which enable tuna species to survive a wider range of circumstances.

It is very hard to keep them in a captive environment. Monterey Bay Aquarium is one of the few aquariums in the world that successfully keep tuna in display.

Types include:

• bluefin tuna, which can grow to 1,500 pounds.
• yellow fin tuna

Tuna is a popular seafood, and in danger from overfishing.

In Polynesian mythology, Tuna is the god of eels who was sentenced to be executed (by the Upolo) after trying to rape Sina (who had grown him in a jar). He asked that his head be buried in the sand and from it, the first coconut grew. He was Hina's lover.
